This table will be provided during the practical, but I'll encourage them to be familiar with it before hand rather than try to make sense of it during the test itself.

2) Basically, the test consists of following the instructions, writing down the observations and making conclusions.Writing observations - the student can use the relevant phrases described in the table Making conclusions - this part is largely dependent on the observations.

Students are usually stressed about making the conclusion but keeping things in perspective. The chemistry practical is "only 7.5%" and the conclusion part is an only small portion. There are more marks to make up for it in the theory papers.

3) The questions are quite varied, so I will not try to "predict" anything more specific. I've seen past year papers on O-level practicals available in the bookshop, you can buy them to have a sense of the questions. If however, you have specific questions, feel free to clarify.
